Hi I am new to ns2 and I am having this problem with xgraph. When I run my file, it keeps giving me this error: ns: finish: Problems found with input data. while executing "exec xgraph tcpTahoe.tr tcpReno.tr tcp793.tr -geometry 800x400" (procedure "finish" line 11)
I have tried running xgraph on other examples and it works. May I know what is the cause of the error? Thank you
